the plant roots move the dirt around revealing new rocks underneath the soil, which then are exposed to erosion.
mechanical weathering
In mechanical weathering, rocks are broken down into smaller pieces without changing their composition. Mechanical weathering is caused by freezing and thawing, release of pressure, plant growth, action of animals, and abrasion.

Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
Plants can cause mechanical weathering by growing into cracks in rocks and breaking them apart as their roots expand. They can also cause chemical weathering by releasing acids and other compounds that break down the minerals in rocks.

Because roots physically encompass and break down soil.
The growth of plant roots is more related to mechanical weathering. As roots grow and extend, they can exert pressure on rocks, causing them to break apart. This process helps in breaking down rocks into smaller pieces and enhancing soil formation.
Moss is biological weathering, actually, because it involves a plant.

Mechanical or physical weathering is a process in which a rock is broken down into smaller pieces by factors such as water absorption or freezing and thawing. It can also be caused by plant root growth.
There are two main types of weathering: mechanical (also called 'physical') and chemical. Pressure release is a form of mechanical weathering. Pressure release usually occurs when rock that has been deeply buried, rises toward the surface due to the erosion of the mass of rock above it. Pressure release causes fractures and exfoliation in the depressurizing rock body. These fractures in the rock make it more susceptible to, and accelerate, other modes of mechanical weathering attack, such as freeze/thaw hydraulics and plant root growth.
